We cover how male factor, non-male factor, poor responders, advanced maternal age, patients using PGS, and others respond to ICSI versus Conventional Insemination. We take a closer look at the specific metrics, like ICSI fertilization rate, needed to quantify a laboratory’s ability. We also delve into the data about how ICSI may increase the rate of birth defects and the urogenital impact to male offspring. We cite over 40 studies and use insights gleaned from interviews with embryologists, andrologists, reproductive urologists and reproductive endocrinologists.
